here the back of the board.

Hi,I wanna know which machine and control board do you have?PedroNas wrote:hi guys my extruder doesnt move when i start a print everything else moves but the extruder does nothing, i have switched the driver and the motor and both of them seem to be just fine, also when i test the extruder with the repetier host it works when i try in the 3d printer itself in the move axis option it makes noise but doesnt move.
Im thinking its the marlin firmware but im not sure, i already have updated the firmware http://www.geeetech.com/forum/viewtopic.php?t=17046 but it looks and acts the same. Anyone has an ideia what might be my problem
